Answer:

- 12 and - 187

Step-by-step explanation:

To evaluate f(- 7) substitute x = - 7 into f(x)

f(- 7) = 2(- 7) + 2 = - 14 + 2 = - 12

Similarly for g(- 4)

g(- 4) = 3(- 4)³ + 5 = 3(- 64) + 5 = - 192 + 5 = - 187

Please help asap!! finding value

notsponge [240]

Hey there :)

The given are 104, 137, 154, 131 and we have to find x
The mean value is 130

Mean = sum of all values divided by total number of values
130 = $\frac{104+137+154+131+x}{5}$

130 x 5 = 526 + x

650 = 526 + x

124 = x

Your answer will be option A) 124
